DETACHABLE POLE FOR VEHICLES.

To all whom it may concern:

Be it known that we, MORIZ HrRseI-I and CARL GREIL, subjects of the Emperor of Austria-Hungary, residing at Ried, in the :Empire of Austria-Hungary, have invented new and useful Improvements in Detachable Poles for Vehicles, of which the following is a specilication.

This invention relates to a mechanism for fastening the poles of vehicles of all kinds in the pole shoe, which fastening can easily be released from the vehicle, so that if the horses'run away the pole may be quickly released and thereby the vehicle together with its passengers escape damage.

The fastening device according to this invention is of the kind already known in which the bolt which retains the pole in the pole shoe is connected permanently with a ever, which lever can be operated from the vehicle by means of a treadle or a traction organ, and which in turning raises the pole bolt and thus releases the connection of the pole with the pole shoe.

The novelty of the present invention consists in the arrangement that the axis of revolution of the lever is arranged revoluble about the axis of revolution of the pole, the lever itself is supported revoluble about the treadle bar, and the axis of revolution of the lever as well as the connecting bolt of the lever with the treadle or that with the pole bolt or of connecting bolts are arranged displaceable in guides of the lever, for the purpose of enabling the lever to follow all the turns ofthe pole.

The invention is illustrated in the draw- `ings as follows: Figure l shows a side elevation Fig. 2 a plan view, andFigB a front view. Figs. 4, 5 land 6 show details of the construction, Figs. 7 and 8 show a modication ofthe device in side elevation and in plan view respectively.

The bolt e which serves to secure the pole a in the poleshoe b possesses a part d, against which there presses a spring 7L arranged within a sleeve f attached to the pole shoe. The other end of the spring presses against a cover g ofthe sleeve f, whereby any unintentional release of the pole bolt is prevented. The bolt chas a cross head i, the ends whereof project through slots y' of the longitudinal support lc of a lever m in the form of a frame,

and are connected with a loop Z engaging with a traction organ Z. Upon the pole shoe t there is secured an upright n, in which is placed a bolt o, which serves as guide for a ring p. The ring p is swiveled in a rod g (Fig. 4), which rod is supported in a box r open underneath and iixed to the lever m. The front and rear wall s olE the box r possess a boring corresponding to the transverse section of the rod g (Fig. 5) through which there passes the rod q. AThe rod has a rib Q, which engages in a slot of the one side wall s of the box fr, whereby a turning of the rod g during its displacement is prevented. By this arrangement the lever m can move by aid of the ring p along the bolt o and at the same time the ring p can make a movement parallel to the longitudinal axis of the lever by aid of the movable rod g. The other end of the lever m is connected by means of ivots t projecting through slots t and its ongitudinal carrier 7c with a part u which is supported revolubly upon a rod e connected to a treadle fr. ln consequence of this construction of the lever m this latter is revoluble about the rod o, while the turning point of the lever is arranged revolubly about the axis of revolution of the pole. The treadle bar o is supported in a iixed neck bearing w with which it has a slot-and-pin connection y and onto it is swiveled the part u by aid of a screw fr iixed at its end.

In order tol release the pole a from the pole shoe the treadle c v or the traction organ Z is actuated. In each case there results a turning of the lever m about the bolt o and the pole bolt c is raised against the pressure of the spring h and the connection of the pole a with the pole shoe b is thus released. If the pole turns with the pole shoe then the carrier ring p of the lever m will be displaced along the bolt 0 and simultaneously the rod g will move correspondingly in the guides oi' the box r, so that the point of revolution of the lever m can execute a longitudinal displacement simultaneously with the turning movement. The compulsory motion of the lever m with the pole is also attained thereby after the connecting bolt t of the lever m together with the treadle bar c and the ends of the cross head i are arranged displaceable in guides t or y' of the lever fm'. It will also suIice if either the connecting bolts t or the ends of the crosshead i were alone arranged to slide'in guide slots of the lever. In this case, however, the slots and the lever ends projecting over the connecting bolts would become too long, so that it is preferable to support all the connecting bolts adjustably in guides of the lever.

Instead of using the above described construction the turning point of the lever m may be secured along a bolt 0 by means of a ring p hrmly attached to the lever fm, the said bolt forming a part of a circle, the center whereof coincides with the axis of revolution of the pole (Figs. 7 and 8). The other portions oi the construction will be as above described. The curving of the bolt 0 into a segment of a circle has the advantage that the longitudinal displacement of the lever is lessened, and thereby also the guideslots at the ends of the lever can be made shorter and the turning of the lever can be effected with greater ease. Moreover as the lever m follows this latter when the pole is turned, the actuation of the device can be effected easily and safely in every position.

The treadle plate instead of being placed at the drivers boX may also be arranged in the interior of the vehicle and be connected with the lever m by means of suitable lever transmission.

An important advantage of the present invention consists in that it can easily be adapted to any kind of vehicle.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 1. The combination of the pole, the pole shoe, a device normally locking the pole and pole shoe together, a treadle, a lever, said device being connected with the treadle and the locking device and having its connection with one` of them a longitudinally yielding one, and means for fulcruming the lever on the pole shoe, said means being connected with the lever between said locking device and the treadle and the lever being shii'table laterally on said means, substantially as described.
